Beit known that I, CHARLE'SI'W, NAcii'rEL, a citizen oi the United States, residingat Jamaica, county of QueensfState of New York, have invented certain new and useful Improvements in Electric Switches, of which the followingis a specification, reference be.- ing had therein to the accompanying draw ing, in which 3 Figure 1 is a face view of the switch; Fig 2 a vertical sectional View on the line Ii -11 of *Fig. 1; and Fig. 3 a similar view on the line HIHI of Fig. 1 showing the switch closed.

The main object of this invention is to pro' videa switch for use in electric circuits, ceedingly simple construction, which; ll be].

durable and easilysecured in place-- A further object of the invention'is to provide a switch which may be very cheaply manufactured and which is particularly well f adapted for use in circuits having eak cur-:

rents, such as toys; ordinary household tools and signals, etc.

which is preferably of Wood. It will, or course, be understood, however, that the base blockmay be of any suitable non-con:

ducting material. The switch bar 2 is '.a

piece of nonconductiiig mate of hard fiber. This bar is she in th drawing as'cylindr'ical from end fend, but, of course, it may be of any suitable. shape in 1 preferably cross-section. Secured to this bar is a metal stripfi, said strip being formed preferably of a piece of wire having its ends 4' tu'rnedfat right angles to the bodyv of the'fstrip andse-t curely fastened in the s vitc hbar. This contact strip is-parallel with thelongitudinal center line of the switchbar and it is placed on said bara suitable distance from the ends thereof. I

' The-switch bar is mounted tooscillate in two hearings or supportsewliich are separated from each other a suitable distance and engage the switch'bar out-side of or beyond the ends of the contact strip. Each bearing is formed of a piece of sheet metal} preferably brass, which is bent upon'itself to form a loop 6 which constitutes a bearing for the switch bar. One end of this strip forms a base iece 7 which is adapted to lie against the ace of the supporting block 1; the other end forminga clamp member 7 and lying on the outer side of the base piece. The extreme the block.

lating movement of the switch bar.

free end of the base piece is bent outward or at right angles to mam-body thereof to form the flange 8 a'gainst'which the circuit wire. is; placed. The extreme end'of the clamp member is bentputwardly'slightly as at 8 to permit the circuit WlIBtO be placed thereunder, the outward bent portions of the base piece and the clamp member constitutin'gaclamp'for the circuit wire.

To secure the bearingsand clamp to 'the supporting block 1 Iuse small nails or tacks 9 which are driven through perforations in the base piece and. the clamp member and into To securethe' block in position and at the same time clamp the circuit Wires in place I employ a long screwilO which is passed through registering perforations in .;the clamp member and the basepiece of-the bearing and through the block 1 into the support 'to vwhich saidlbloclr is to be connected. The screws 10, therefore, serve not only as circuit-wire securing means, but alsoas a v :means foi' secur'ing the switch block in place. .Referring. to the various parts by nu-- .inerals, 1 designates the base of the switch;

Bythisme ans I avoid the use of separate Wire fastening means;

ing loop 6, as shownclearlyin Fi -1.. These. contact lips are in suchpos'itionthat the ends 'of' 'tlie" contact strip may/be forced under them, saidlips being sufiicientl'y resilientto yield and permitsaid'strip toforce them out vward. To limit the rotary:oscillating movement'of the switch bar one 'of'the bearingloops' is slotted circun ferentiallyas at 13 in Figs. land Secured to the switch bar andpassing throu h said slot is apiii-"ld, the length of; the slot limiting the eXtent of oscill l also holds the switch-harm the ,bearings agaiiistundue longit-uc liiial movement; =To enable the si'v tch'bar to be readily turned-inbearings I provicl'e' an operating handle 15 securedto oneend thereof and projecting radially therefrom."

From the foregoing it Willbe evident that I [have plOVltlQll an extremely 'simpleelectric' The pin Having thus described my invention what I claim as-new and desire to secure by Letters Patent,i's': I

1. An electric switch comprising a nonconducting support, two bearings-thereon, a rotary oscillating'switch bar mounted in said bearings, a contact strip carried by said switch bar, a contact'lip carried by each ofsaid bearings and adapted to be engaged by the contact strip on the switch bar, wire clamping means formed'int'egral with the bearings, and means. for closing the wire clamping means, said means also serving to secure the switch bar in place.

2. An electric switch comprising a rotary oscillating switch bar of non-conducting material, a contact strip carried thereby and eX- tending longitudinally thereof, a pair of bearings for said bar,'each of saidbearings being l'ormed of astrip of metal bent upon itself to form bearing loops to receive the switch bar, the two ends of said strip being brought together to form a wire clamp, and a contact lip formed integral with said" strip and partly embracing the switch bar and adapted to be engaged by the contact strip of said bar.

3. An electric switch. comprising a rotary oscillating contact bar of non-conducting material, a contact stri secured thereto and extending longitudinal y thereof, means for supporting said switch bar, said means consisting of two supporting devices each ofwhich consists of a strip of sheet metal bent upon itself to form a bearing loop, one end of said strip constituting a-base piece and formingone inember of a wirewclamp, the otherend of said strip lying flat. against thebase iece and having its extreme and bent toform the other member of, the wire clamp and a contact lip formed integral with one of said ends and partially embracing the switch.
